| Abstract: | A new spectrophotometric method for the rapid determination of chemical oxygen demand(COD) in water quality is described.the sample was digested in a microwave oven.The conditions for microwave digestion and determination are discussed.The proposed method has been applied to the analysis of environmental waste water and sewage samples and results obtained are satisfactory both in accuracy and precision.The method is effective and more convenient for the determinations of COD in samples. |
